In order to determine the best match length of slotted AVC (opening angle is 100°, slot size is 2mm), the effect of combustor length on combustion efficiency, the outlet temperature distribution and radial temperature distribution were numerically calculated. The results show the best match length of combustor is 800 mm, on the basis of this structure, the third blunt body was added for forming the double-cavity AVC, studies suggest that when the length of the second cavity is L2/L₁ = 1.2, slot size of the third blunt body is L3/H = 0. 6, AVC has advantages of good flow field, stable combustion, high temperature distribution.
